I'm after motherboard Socket 939 that supports DDR2 memory
Still looking....seems all of them are still DDR only.
From one recent article:
Quote:
On the other hand, suppose AMD won't be too quick to support DDR2. Then the standard will be a handy tool for Intel to exert pressure on its rival, as it will create another obstacle for users' free interplatform transition. Indeed, it is still unclear whether the new AMD Socket 939 platform will be adapted for DDR2, and besides, the integration of the memory controller into the CPU creates problems too. Thus, AMD will have to support only DDR for quite a while. If Intel is quick enough to make DDR2 the main memory for its future Socket 775, then Intel and AMD platforms will become even less compatible (chipsets, boards, CPUs, and now memory types). Should this situation occur, new module and chip manufacturers (not large-scale ones) will appear that will either provide a full support for DDR2 or reject it altogether, thus choosing one of the rival platforms.
Taking form a point made in Bistro's quote... It is impractical at this time to have DDR2 support for amd64 socket 939 processors, in particular because (as the article says) the memory controller is built in to the processor package. And as yet, this built-in controlle is not compatible with ddr2. Besides, there is not really anything yet to be gained by DDR2, even in the intel world (where there is DDR2 support) because of existing bus speeds and the effects they have on latencies and bandwidth utililization.
the only real use for memory capable of such speed at this time is in graphics cards, and those have already moved up to GDDR3
